If a recipe has SRC_URI_append in it to add items to SRC_URI, then devtool update-recipe will end up duplicating those items when it comes to edit the SRC_URI value. I noticed this when doing devtool modify on the kernel; since 94abdb2eea610b174064978d2fb8354a6231fc0c we have a patch in linux-yocto added using SRC_URI_append. The only practical means of handling this that I can think of is to have devtool update-recipe add an _append (or update the existing _append) itself, otherwise even if we fix the duplication the patches will end up out-of-order.
